If you're here looking for a place picker you have probably read this:
As of the end of January 2019, Google deprecated the so useful Place Picker bundled in the Places SDK for Android. The main reason was due the new pricing model of the Places API.
PING Place Picker is here to help you to (almost) plug-and-play replace the original Google's Place Picker.
Different than Google's Place Picker, PING by default doesn't search for places according to where the user is pointing the map to. Instead, it shows only the nearby places in the current location.
This was intentional and the reason is simple. By using the /nearbysearch from Google Places Web API we are going to be charged a lot for each map movement.
According to Nearby Search pricing each request to the API is going to cost 0.04 USD per each (40.00 USD per 1000).
To avoid the extra cost of /nearbysearch, PING relies on Place API's findCurrentPlace() that is going to cost 0.030 USD per each (30.00 USD per 1000).
Moreover, we don't fire a new request when the user moves the map.
If you do want to fetch places from a custom location or refresh them when the user moves the map, you must enable /nearbysearch queries in PING.
To do that, enable this flag in your project:
<bool name="enable_nearby_search">true</bool>By doing so, PING behavior will be slightly changed:
- All places will be fetched by /nearbysearch queries.
- You get a button to refresh the the places for the current location.
- You can set the initial map position to get the places from via
pingBuilder.setLatLng(LatLng)
PING is based entirely on Google Places and MAPs APIs. Google has the biggest places database available to us developers with most up to date and curated places information.
It is worth to notice that Google provides US$ 200 (free) per month to be used with Places API. This should be more than enough for small applications that rely on Places data.
Add Jitpack in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
// Places library
implementation 'com.google.android.libraries.places:places:1.1.0'
// PING Place Picker
implementation 'com.github.rtchagas:pingplacepicker:1.1.+'
}
- Add Google Play Services to your project - How to
- Sign up for API keys - How to
- Add the Android API key to your AndroidManifest file as in the sample project.
- Optional but strongly recommended to enable R8 in you gradle.properties file
Check the sample project for a full working example.
private fun showPlacePicker() {
val builder = PingPlacePicker.IntentBuilder()
builder.setAndroidApiKey("YOUR_ANDROID_API_KEY")
.setMapsApiKey("YOUR_MAPS_API_KEY")
// If you want to set a initial location rather then the current device location.
// NOTE: enable_nearby_search MUST be true.
// builder.setLatLng(LatLng(37.4219999, -122.0862462))
try {
val placeIntent = pingBuilder.build(this)
startActivityForResult(placeIntent, REQUEST_PLACE_PICKER)
}
catch (ex: Exception) {
toast("Google Play Services is not Available")
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if ((requestCode == REQUEST_PLACE_PICKER) && (resultCode == Activity.RESULT_OK)) {
val place: Place? = PingPlacePicker.getPlace(data!!)
toast("You selected: ${place?.name}")
}
} private void showPlacePicker() {
PingPlacePicker.IntentBuilder builder = new PingPlacePicker.IntentBuilder();
builder.setAndroidApiKey("YOUR_ANDROID_API_KEY")
.setMapsApiKey("YOUR_MAPS_API_KEY");
// If you want to set a initial location rather then the current device location.
// NOTE: enable_nearby_search MUST be true.
// builder.setLatLng(new LatLng(37.4219999, -122.0862462))
try {
Intent placeIntent = builder.build(getActivity());
startActivityForResult(placeIntent, REQUEST_PLACE_PICKER);
}
catch (Exception ex) {
// Google Play services is not available...
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if ((requestCode == REQUEST_PLACE_PICKER) && (resultCode == RESULT_OK)) {
Place place = PingPlacePicker.getPlace(data);
if (place != null) {
Toast.makeText(this, "You selected the place: " + place.getName(), Toast.LENGTH_SHORT).show();
}
}
}PING needs two API keys in order to work.
It was decided to split the API keys to clearly distinguish what you're going to be charged for. Also, the Places Web API and the Geocoding API don't allow an Android API key to be used. To not expose an unrestricted key for all APIs, the Maps API key is now required.
| Key | Restriction | Purpose |
|---|---|---|
| Android key | Android Applications | Used as the Places API key. Main purpose is to retrieve the current places and place details. |
| Maps key | APIs: Geocoding and Places API only | Used to fetch nearby places through Places Web API and perform reverse geocoding on the current user position. That is, discover the address that the user is current pointing to. Your key should look like this. |
TIP: It is strongly recommended to not expose your Maps API key in your resource files. Anyone could decompile your apk and have access to that key. To avoid this, the key should be at least obfuscated. A nice approach is to save the key in the cloud through "Firebase remote config" and fetch it at runtime.
As some features are charged by Google, you can alter the default PING Place Picker behaviour by overriding below resources:
<!-- 0.002 USD per each (2.00 USD per 1000) -->
<bool name="show_confirmation_photo">true</bool>
<!-- 0.007 USD per each (7.00 USD per 1000) -->
<bool name="show_confirmation_map">true</bool>Let's together make PING awesome!
